Resident Instruction: Improving End-of-Year Medical Student Ultrasound Performance.

Background And Objectives: Having a limited number of trained faculty is a barrier to successful incorporation of ultrasound into undergraduate medical education. We evaluated the effectiveness of a resident-led extended focused assessment with sonography in trauma (eFAST) session administered to fourth-year medical students during their emergency medicine clerkship by measuring students' end-of-year eFAST performance and confidence.

Methods: This was a single-site cross-sectional study of all graduating medical students enrolled in fourth-year clerkships between May 1, 2022 and April 30, 2023.

Point-of-care ultrasound associated with shorter length of stay than computed tomography for renal colic.

Background: Despite similar diagnostic effectiveness for renal colic, computed tomography (CT) is more resource intensive than point-of-care ultrasound (PoCUS). We sought to compare Emergency Department (ED) length of stay (LOS) among patients with renal colic according to imaging modality utilized. We secondarily compared rates of infection, return ED visits, missed significant pathology, and urologic intervention.
